GUSTAVE J. MARTEL, OF CHICAGO, ILLINOIS.

TIRE-PATCHING DEVICE.

To all whom it may concern:

Be it known that I, GUs'rAvE J. MARTEL, a citizen of the United States,and a resident of the city of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements inTire-Patching Devices, of which the following is a specification.

My invention relates to improvements in patching devices for pneumatictires and has for its object the production of a device of thischaracter which may be readily and quickly applied for use and asreadily and expeditiously detached when desired.

A further object is the provision of a patching device which will be ofsimple and economical construction, hence of low cost of manufacture,and one which will be of great efficiency in use.

Other objects will appear hereinafter.

With these objects in View my invention consists in the combination andarrangements of parts hereinafter described and claimed.

My invention will be best understood by reference to the accompanyingdrawings forming a part of this specification and in which,

Figure 1 is a fragmentary side elevation of an ordinary pneumatic tire,and a rim carrying the same to which is applied a patching deviceembodying the preferred form of my invention, and Fig. 2 is a transversesection taken on substantially line w-w of Fig. 1.

Referring now to the drawings particularly to Figs. 1 and 2, 1 indicatesa rim of ordinary construction and design in which is secured a tirecasing 2, 8 indicating the air tube arranged in the latter. Detachablysecured upon the rim 1 is a clamp comprising the jaw members 4 and 5,said jaw members engaging the edges of said rim at opposite points, thecontacting surfaces thereof being so formed as to adapt the same tosnugly engage said edges of said rim. Formed integrally with the jawmember 4 is a transversely extending shank 6 which extends below the rim1 in close proximity thereto, the outer end portion of said shankengaging an alining slot or socket 7 provided in the lower end portionof the jaw member 5, said slot and shank being of corresponding crosssectional form so that relative rotary movement of the jaw members 4 and5 is prevented. The outer extrem- Specification of Letters Patent.

ity 8 of the shank 6 is reduced and screw threaded for the reception ofa nut 9, the latter being adapted when threaded thereon into abuttingwith the outer side of the jaw member 5 to force said jaw members intoclamping engagement with the opposite edges of the rim 1. The nut 9 isheld in any position to adjustment upon the shank end 8 that is againstretrograde rotation thereon by means of an ordinary lock nut 10. Withthe arrangement then as set forth in application thereof to a rim 1 isonly re quired after arranging the jaw members 4 and 5 with their innersurfaces engaging the sides of the rim to apply the nuts 9 and 10 whichserve to maintain the same in clamping relation. In order to preventslipping of the clamp upon the rim contacting surfaces of the jaw member5 is provided with a plurality of inwardly project'- ing teeth or burs11 which are adapted to pierce the adjacent side of the rim when saidjaw member is forced into engagement therewith.

The outer end portion of the member 4 is formed into a transverselyextending elongated bar 12 to which is rigidly secured preferably bymeans of screws 13 and nuts 14 threaded upon said screws one end of thepatching strap 15. The latter is formed of any suitable durable flexiblematerial, preferably leather, and the same projects from the outer end12 of the jaw member 4 around the tread portion of the tire, theopposite end thereof being rigidly secured, preferably by means ofscrews 16 and nuts 17 to a yoke or bar 18. Formed centrally upon theyoke 18 are spaced depending integral projections 19 which looselyengage perforated lugs 20 formed integral with and laterally projectingfrom the jaw member 5. The lower end portion of the projections 19 arescrew threaded, nuts 20 threaded thereon and resting in engagement withthe under sides of the lugs 20 serving to secure the same to the jawmember 5. The arrangement is such, as will be observed, that bypositively rotating said nuts upon said projections the yoke 18 may belowered, and hence the strap 15 tightened about the tire, so as to adaptsaid strap to effectually serve as a reinforcing means for the tire.Lock nuts 22 threaded upon the projections 19 against the outer edges ofthe nuts 20 serve an obvious purpose.

A patching device of the construction as thereby.

i carrying my invention into eifect this may be varied somewhat withoutdeparting from the spirit of the claim, and hence I do not desire to belimited as to the precise details of construction set forth but desireto avail myself of such variations and modification as fall within thescope of the appended claim.

Having describedmy invention what I 5 deem as-new and desire to secureby Letters Patent is:

In a patching dev ce for pneumatic tires,

the combination with a rim and a tire mounted thereon, of a flexiblepatching strap extending over the tread portion of said tire; and meansfor tightening sa d strap about said tire, said means comprising a clampdetachably clamped upon said rim; a rigid connection between one side ofsaid clamp and one end of said strap; a yoke secured to the other end ofsaid strap and having threaded projections passing through slots in theopposite side ofsaid clamp; and means threaded upon said projections fortightening said strap about said ti re, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
